Methods, systems, apparatuses, and computer program products are provided herein for determining the handedness of input provided by a user via a touch interface. For instance, for each touch-based input detected, a score indicating a probability whether the touch-based input was inputted by a particular hand of the user is generated. A classification for the touch-based input is then generated based on a drift diffusion model-based technique in which inter-dependencies between a series of touch-based input are approximated. The determined classifications are used to determine the handedness of the user.

A display device includes a display unit including a plurality of light emitting areas, a plurality of touch electrodes disposed between the plurality of light emitting areas to sense a touch, a plurality of light blocking pattern layers formed by covering intersection areas of driving electrodes and sensing electrodes among the plurality of touch electrodes, a plurality of connection electrodes formed on the plurality of light blocking pattern layers to electrically connect the driving electrodes or the sensing electrodes adjacent to each other, and a plurality of code patterns formed of the same material as the plurality of light blocking pattern layers through the same process.

Provided is a position detection circuit for detecting a position of an electronic pen and a position of a passive pointer on a touch surface disposed on a capacitive touch sensor constituted by a plurality of sensor electrodes arranged two-dimensionally, the electronic pen being configured to be capable of transmitting a pen signal, the passive pointer not transmitting any signal, the position detection circuit configured to detect a touch position indicative of the position of the passive pointer, and output the touch position if a size of a region forming the touch position is within a predetermined range, in which, if the electronic pen was in contact with the touch surface and becomes detached therefrom, the output of the touch position is temporarily inhibited.

In an embodiment, various active pens may be searched for in every frame, so that various active pens may operate in a touch sensing system.

A pen apparatus with a pressure sensitive tip mechanism that internally generates pressure, tilt, and/or barrel rotation through the use of a multi-axis measurement scheme with simultaneous transmit, receive, and sensing driver capability operable in conjunction with a receiving system or in a relative stand-alone manner. Signaling schemes are provided for operating the pen apparatus to achieve improved function. Systems and methods are provided for operating a pen, and for operating a pen with a touch sensor system. Drive/receive circuitry and methods of driving and receiving sensor electrode signals are provided that allow digital I/O pins to be used to interface with touch sensor electrodes. This circuitry may be operated in modes to sense various combinations of signals coupled within a pen, or from outside of a pen.

A channel driver circuit includes a differential module and a driver module. In some examples, the channel driver circuit also includes a sigma-delta module. The differential module receives, via a single node of a load, a channel driving signal that is provided to the load at the single node (e.g., that is based on an electrical characteristic of the load) and generates an analog error signal that is based on the channel driving signal and a reference signal. The driver module is coupled to the differential module and generates the channel driving signal based on the analog error signal or a digital error signal corresponding to the analog error signal and transmits the channel driving signal via the single node to the load. The channel driver circuit simultaneously transmits the channel driving signal to the load at the single node and senses the channel driving signal at the single node.

An air mouse mode implementation method includes establishing, by an electronic device, a communication connection to a stylus through BLUETOOTH, sending, by the electronic device, notification information to the stylus through the communication connection when detecting a screen casting event of the electronic device, where the notification information instructs to enter an air mouse mode, receiving, by the electronic device, a determining instruction from the stylus through the communication connection, entering, by the electronic device, the air mouse mode based on the determining instruction, and modifying, from an arrow icon to a dot icon and by the electronic device, an indication icon corresponding to the stylus.

An example apparatus Includes a first hinge, a first housing having a hinge region and a support panel, where the support panel is to extend from the hinge region. The apparatus also Includes a first display device rotatably coupled to the support panel via the first hinge, a second housing having a set of external electrical contact to provide power to a removable input device, a second hinge to rotatably couple the first housing to the second housing, and a second display device fixedly coupled to the second housing.

An electronic apparatus includes a host, a main display, a keyboard, an auxiliary display, and a supporting mechanism. The main display is pivotally connected to the host. The keyboard is slidably disposed on the host. The auxiliary display is disposed on the host and is arranged side by side with the keyboard. The auxiliary display includes a movable end and a lifting end, the keyboard contacts the movable end, and the movable end is slidably connected to the host. The supporting mechanism includes a first link, a second link, and a third link. The first link is slidably connected to the host and is pivotally connected to the second link. The second link is pivotally connected to the host and is pivotally connected to the third link. The third link is pivotally connected to the lifting end.

An information input device includes: a communication interface configured to communicate with each of a first external apparatus that operates using a first operating system and a second external apparatus that operates using a second operating system; and a controller configured to operate in a first mode corresponding to a first driver used by the first external apparatus when transferring data to the first external apparatus, and operate in a second mode corresponding to a second driver different from the first driver and used by the second external apparatus when transferring data to the second external apparatus.
